Some form of WiFi oriented traffic generator

If anyone has a copy of ixChariot with key, that would be fantastic, since I'm looking for some form of realistic traffic generator to simulate large volumes of normal end-user network traffic across a WiFi network build. iPerf and flinging large files from point A to point B doesn't really give a true picture of how the network would handle it. If anyone doesn't have Chariot, but has a ton of realistic .pcap files I can use Wireshark's traffic generator to run, or even other free tools I can use, thought would be nice, too. I've just heard great things about ixChariot, is all. I found some tools online a little while ago, but they all seem to be more concerned with with security flaw detection, or killing WAN links. : /
